Application April 2,

1 Claim.

Among the objects of the invention are to provide a bottle closurehaving against the entrance therethrough of bacteria into the bottle; toprovide an improved closure,

having a pouring spout, for milk bottles which tended.

Figure 4 is a bottom plan view of the closure Figure is a perspectiveview mounted on a milk bottle and of the closure as with the pouringspout extended.

sertion in 'made of disk b or straight divergent The disky means of an Aportion of the tab, adjacent its free end, is

Qremoved therefrom along the a as to provide a recess chordal lint i3 soI 4 which permits the user to insert his finger nail therein tofacilitate movement oi the tab.

1935, Serial No. 14,339 (Cl. 215-51) Mounted on the back of the section8 is a circular sheet I5 of relatively stiff material such as isprovided with a central portion is outlined by a circular slit II, apair of divergent scores l8 and a transverse slit l9. Each of the scoresand slits mentioned above are disposed so that they lie in registry withthe separated from the body of the sheet l5 by curved slits 2| whichjoin the slit H, at one end thereof, and at the other end join thetransverse slit IS. The purpose of the slit I9 is to permit separationof the portion Hi from the remainder of the sheet l5, when the spout isdrawn through the aperture, for the reason that, in the absence of theslit, the portionof the sheet l5 adjacent the hinge of the spout would,due to being bent about a larger radius than the material of the disk,be liable to rupture.

All of the portions of the sheet l5 are adhesively secured to thesection 8 with the exception of the wings 20 which maybe prevented fromadhering thereto by the application, to the areas underlying the wings,of a coating 22 of paraifin.

It will thus be seen that when the tab portion 9 is moved forward theportion It will, due to its connection therewith,be carried through theaperture 23 created in the section 8 by the removal of the tab 9therefrom. Simultaneously with the movement of the tab 9 the wings 20will assume positions vertical to the plane of the portion l6, as shownin Figures 3 and 5. This is caused by the curved edges 24 of the wingsbearing against the straight sides of the aperture 23 as they are drawntherethrough.

When the pouring spout is in the position indicated in Figure 5 thecontents of the bottle may i be poured therefrom through the aperture 23and, when it is desired to re-seal the bottle, the spout may be movedback to its normal position flush with the surface of the section 8whereupon ,the aperture 23 will be closed.

In order to seal the closure against the entrance of bacteria or othercontaminating matter into the bottle, it is proposed to provide asealing sheet 25 of cellophane or other like material which may beadhesively attached to the top surface of the closure. It is preferablethat the cellophane be attached by means of a tacky or nonhardeningadhesive so that the sealing sheet may be removed and replaced, tore-seal the bottle, several times without the adhesive losing itsgripping properties.

Having thus described the invention. it will be seen that an improvedclosure for bottles or the like has been provided which greatlyfacilitates the removal of the contents thereof, and at the 5 same timeprovides means for thoroughly sealing the bottle against the entrancethereinto of contaminating matter. In addition to these features theprovision of a pouring spout, oi the proportions indicated, enables theuser to pour the con- 10 tents from wide necked bottles in aconcentrated stream with the result that the stream may be more readilycontrolled and losses due to spillage, in transferring the contents ofthe bottle to other containers, are greatly reduced.

15 What I claim is:

A bottle closure comprising a disk of relatively thick fibrous materialhaving a slit therein defining an opening and a tab complemental to anddisposed within said opening, said tab being integrally hinged to saiddisk at a side of said opening for free movement into and out of saidopening so as to open and close the latter, a parent sheet of relativelythin stii'! material overlying one race of said disk, said parent sheethaving therein a continuous slit defining a central portionseparablefrom the remainder of the sheet, said remainder of the sheet beingadhesively attached to the disk and said central portion or the sheetcomprising an area overlying and adhesively joined to said tab and freewing-shaped areas extending from opposite edges of said tab andoverlying surfaces oi. said disk at each side of the opening thereof,and one portion of the continuous slit defining the separable centralportion of said parent sheet being disposed immediately overlying thehinge of said tab.
